본 발명은 이동통신단말기의 회로기판에 관한 것으로서, 특히 확장가능한 슬 롯타입구조를 갖는 회로기판구조에 대한 것이다.The present invention relates to a circuit board of a mobile communication terminal, and more particularly to a circuit board structure having an expandable slot type structure.

종래의 이동통신단말기에 있어서, 이동통신단말기의 PCB(Printed circuit board ; 인쇄회로기판)에는 MSM(Mobile Station Modem), 각종 필터(Filter), 전력 및 구동 증폭기(Power AMP or Drive AMP), 듀플렉서(Duplexer), BBA(Base Band Analog.), 저잡음 증폭기(Low Noise AMP), 및 아이솔레이터(Isolator) 등과 같은 각종소자들과, 다수개의 DC 전원 라인 및 다수개의 그라운드 라인 등과 같은 각종 라인들이 마운트된다. In a conventional mobile communication terminal, a printed circuit board (PCB) of a mobile communication terminal includes a mobile station modem (MSM), various filters, power and drive amplifiers, and a duplexer (PC). Various elements such as a duplexer, a base band analog (BBA), a low noise amplifier, and an isolator, and various lines such as a plurality of DC power lines and a plurality of ground lines are mounted.

물론 이동통신단말기가 다기능을 지원하도록 구성됨에 따라 메모리, 카메라, 오디오 등이 더 구성된다. 즉 메인 PCB에 위에서 기술한 소자들을 함께 마운트하게 된다. Of course, as the mobile terminal is configured to support multi-function, memory, camera, audio, etc. are further configured. That is, the above-described devices are mounted together on the main PCB.

따라서 이러한 종래의 PCB는 확장이 가능하지 못하다는 단점이 있었다. 즉 메인PCB가 한번 솔더링(soldering)되어 버리면 부품들을 따로 분리하여 업그레이드한다는 것이 불가능하였다. 또한 각모델별로 각각의 디자인에 맞도록 하드웨어를 설계함으로써 부품공용화 및 개발시간이 지연되는 단점이 있었다.Therefore, this conventional PCB has a disadvantage that it is not scalable. In other words, once the main PCB was soldered, it was impossible to upgrade the parts separately. In addition, by designing the hardware for each model for each model, there was a disadvantage that the parts commonization and development time is delayed.

이러한 문제점을 해결하고자 안출된 것으로서, 본 발명은 부품공용화 및 개발시간을 줄이고 확장이 가능한 인쇄회로기판구조를 제공하는데 그 목적을 두고 있다. SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a printed circuit board structure that can reduce component commonization and development time and can be expanded.

상기 목적을 이루기 위하여 본 발명은, 회로배선이 되어 있으며 적어도 한면 에 삽입홈이 형성되어 있는 슬롯이 일정간격을 두고 다수개 배치되는 메인PCB와, 슬롯의 삽입홈에 삽입되어 체결되며 회로부품을 포함하는 인입출 가능한 카드타입의 슬롯모듈과, 메인PCB에 조립되는 내장안테나를 포함하는 확장가능한 이동통신단말기의 인쇄회로기판을 제공한다.In order to achieve the above object, the present invention, the circuit wiring and the insertion groove is formed on at least one side of the slot is a plurality of main PCB is arranged at a predetermined interval, and inserted into the insertion groove of the slot and fastened to include a circuit component The present invention provides a printed circuit board of an expandable mobile communication terminal including a drawable card type slot module and a built-in antenna assembled to a main PCB.

이때, 슬롯모듈의 적어도 한쪽면에는 신호 또는 전도를 위한 수골드핑거부가 형성될 수 있다.In this case, a male gold finger for signal or conduction may be formed on at least one side of the slot module.

또한, 슬롯의 삽입홈에는 슬롯모듈이 인입되었을 때 수골드핑거부가 정합되도록 적어도 한면에 암골드핑거부가 형성되어 있는 것이 특징이다.In addition, the insertion groove of the slot is characterized in that the female gold finger is formed on at least one surface so that the male gold finger is matched when the slot module is inserted.

슬롯과 슬롯모듈의 체결구조는 상기 슬롯모듈이 인입출되도록 핑거부가 형성되어 있는 슬롯과, 적어도 한면에 상기 핑거부에 삽입되도록 하는 슬롯홈이 형성되어 있으며, 상기 슬롯홈 안쪽에 신호 또는 전도를 위한 암골드핑거부가 형성되어 있는 슬롯모듈로 구성되는 다른 구조일 수 있다.The fastening structure of the slot and the slot module has a slot in which a finger portion is formed to draw in and out of the slot module, and a slot groove is formed in at least one surface to be inserted into the finger portion. It may be another structure consisting of a slot module in which the female gold fingers are formed.

따라서 메인PCB에 부품별로 슬롯모듈을 구성함으로써 모델간 변경 및 확장이 가능하게 된다.Therefore, it is possible to change and expand between models by configuring the slot module for each part in the main PCB.

이하, 첨부된 도면을 참조하여 본 발명에 따른 일실시예를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment according to the present invention.

도 1은 본 발명의 일실시예에 따른 회로기판의 분해도이다. 1 is an exploded view of a circuit board according to an embodiment of the present invention.

본 발명의 일실시예에 따른 인쇄회로기판은 메인PCB(10), 슬롯(13), 내장안테나(15), 슬롯모듈(17)이 구성된다. 메인PCB(10)에는 양면 또는 적층 된 기판에 각층간의 필요한 회로도선이 배선된다. 따라서 이 기판에 필요한 부품들이 솔더링되어 온전한 메인PCB가 된다. The printed circuit board according to the exemplary embodiment of the present invention includes a main PCB 10, a slot 13, an internal antenna 15, and a slot module 17. The main PCB 10 is wired with necessary circuit diagrams between the layers on both sides or stacked substrates. As a result, the components required for this board are soldered into an intact main PCB.

메인PCB(10)에는 슬롯(13)의 핀(16)을 고정체결하기 위한 홀(미도시)이 펀칭되어 다수개 존재하게 된다. 이 홀(미도시)에 슬롯(13)이 결합되면 슬롯모듈(17)이 삽입가능하게 되는데 이를 보여주는 도면이 도 2에 도시된다. A plurality of holes (not shown) are punched in the main PCB 10 to fix the pins 16 of the slot 13. When the slot 13 is coupled to the hole (not shown), the slot module 17 is insertable, which is shown in FIG. 2.

도 2는 메인PCB(10)에 슬롯(13)이 조립결합되고 이 슬롯(13)에 슬롯모듈(17)을 밀어서 끼워 넣으면 고정되게 된다. 즉 슬롯(13)들이 일정간격을 두고 메인PCB(10)에 배치됨으로써 두 슬롯(13)사이에 일정한 간격이 형성되고, 이 간격에 슬롯모듈(17)을 삽입하게 하는 구조이다. 이와함께 내장안테나(15)가 결합된다.2 shows that the slot 13 is assembled to the main PCB 10 and the slot module 17 is pushed into the slot 13 to be fixed. That is, the slots 13 are arranged in the main PCB 10 at regular intervals so that a constant gap is formed between the two slots 13, and the slot module 17 is inserted into the gaps. The built-in antenna 15 is combined with it.

물론 슬롯(13)에는 삽입홈(30)이 좌우측면에 형성되어 있게 되는데 이를 보여주는 도면이 도 3에 도시된다. 즉 도 3은 도 2에서 A-A'축으로 절개한 면을 보여주는 단면도로써 슬롯(13)사이에 슬롯모듈(17)이 삽입되어 있는 구조를 보여준다.Of course, the slot 13 has an insertion groove 30 is formed on the left and right sides, which is shown in FIG. That is, FIG. 3 is a cross-sectional view showing a plane cut along the line A-A 'in FIG. 2 and shows a structure in which the slot module 17 is inserted between the slots 13.

즉 한쪽의 슬롯에는 삽입홈(30)이 좌우측의 양쪽면에 형성되어 있고 반대편의 슬롯에는 삽입홈(30)이 좌측면에만 형성되어 있어 슬롯모듈(17)이 삽입되어 있을 수 있게 된다. 물론 다른 삽입홈에도 슬롯모듈(17)이 삽입가능하다. That is, the insertion slot 30 is formed on both sides of the left and right sides of one slot, and the insertion slot 30 is formed only on the left side of the slot on the opposite side so that the slot module 17 can be inserted. Of course, the slot module 17 can be inserted into another insertion groove.

이 삽입홈(30)에는 슬롯모듈(17)이 삽입되어 슬롯모듈에 신호 또는 도전되도록 하는 암골드핑거부(미도시)가 형성된다. 물론 이 암골드핑거부에 정합되도록 슬롯모듈(17)에도 수골드핑거부가 형성되게 된다. 이를 보이는 도면이 도 4에 도시된다. 즉 슬롯모듈(17)에는 슬롯모듈의 외관을 형성하는 슬롯모듈몸체(42)와 이 슬롯모듈몸체(42)의 한쪽면 또는 양쪽면에 형성되는 수골드핑거부(40)가 구성된다.The insertion groove 30 is formed with a female gold finger (not shown) is inserted into the slot module 17 to be signaled or conductive to the slot module. Of course, the male gold finger is also formed in the slot module 17 so as to match the female gold finger. A diagram showing this is shown in FIG. 4. That is, the slot module 17 includes a slot module body 42 forming the exterior of the slot module and a male gold finger 40 formed on one or both sides of the slot module body 42.

슬롯모듈(16)은 전술한 메인PCB(10)와 달리 확장가능하도록 한 카드타입이다. 따라서 각 버전별 또는 각 모델별로 다양한 부품이 마운트된다. 또한 슬롯모듈(16)은 기능별로 분리하여 구성하는 것이 바람직하다. The slot module 16 is a card type that is expandable unlike the main PCB 10 described above. Therefore, different parts are mounted for each version or each model. In addition, the slot module 16 is preferably configured separately for each function.

예를들면 MSM슬롯모듈, RF슬롯모듈, 오디오슬롯모듈별로 구성하는 것이다. 즉 MSM(mobile station modem)슬롯모듈에는 MSM이 버전별로 구성되고 여기에 멀티칩팩키지가 조합됨으로써 다양한 모듈이 가능하다. 또한 이 MSM슬롯모듈은 전원, 엘씨디, 베이스밴드 인터페이스에 연결되게 된다. For example, MSM slot module, RF slot module, and audio slot module are configured. In other words, the MSM is configured in a MSM slot module, and a multi-chip package is combined with the MSM, thereby enabling various modules. The MSM slot module is also connected to the power, LCD, and baseband interfaces.

RF슬롯모듈은 DCN(Data core network) 또는 PCS와 연결되기 위한 무선회로모듈을 조합하여 모델별로 다양하게 구성된다. 따라서 전원, /Q 데이터, 클럭부 인터페이스와 연결된다. The RF slot module is configured in various ways by combining a wireless circuit module for connecting to a DCN (Data Core Network) or PCS. Therefore, it is connected to power, / Q data and clock interface.

오디오(Audio)슬롯모듈은 midi와 오디오앰프가 주요부품이 되며, 전원, 데이터, 오디오출력단 인터페이스와 연결되게 된다. The audio slot module consists of the midi and the audio amplifier, and is connected to the power, data and audio output interface.

물론 이외에도 다양한 주요부품을 슬롯모듈로 구성하면 슬롯모듈만 바꾸어 컴퓨터의 카드처럼 슬롯에 끼워넣게 됨으로써 쉽게 모델변경 및 업그레이드가 가능하다. 즉 예를들면 메인PCB(10)에 MSM6100 + MCP(multi-chip package)로 구성되는 MSM슬롯모듈이 삽입되어 있었다면, 이 슬롯모듈을 빼고 MSM 6500 + MCP로 구성되는 MSM슬롯모듈을 교체하여 삽입함으로써 업그레이드 또는 모델변경이 가능하게 되는 것이다.Of course, if various major components are configured as slot modules, only the slot module can be changed and inserted into the slot like a computer card, thereby making it easy to change and upgrade the model. For example, if the MSM slot module consisting of MSM6100 + MCP (multi-chip package) is inserted in the main PCB 10, by removing the slot module and replacing and inserting the MSM slot module consisting of MSM 6500 + MCP Upgrades or model changes are possible.

도 5는 본 발명의 일실시예에 따른 슬롯구조의 다른 단면도이다. 즉 도 3은 삽입홈(30)이 슬롯(13)에 형성되고 수골드핑거부(40)는 슬롯모듈(17)에 형성되어 있으나, 이와달리 도 5는 핑거부(51)가 슬롯(13)에 형성되어 있는 것이다. 그리고 슬롯홈(50)은 슬롯모듈(17)에 형성되어 있게 된다. 물론 슬롯홈(50)이나 핑거부(51)는 도 3과 도 4에서 기술한 삽입홈(30), 수골드핑거부(40)와 동일한 구조이나 혼동을 방지하기 위하여 다른명칭을 사용한 예에 불과하다.5 is another cross-sectional view of a slot structure according to an embodiment of the present invention. That is, FIG. 3 shows that the insertion groove 30 is formed in the slot 13 and the male gold finger 40 is formed in the slot module 17. In contrast, FIG. It is formed in. And the slot groove 50 is formed in the slot module (17). Of course, the slot groove 50 or the finger portion 51 is just an example of using the other names to prevent the same structure or confusion with the insertion groove 30, male gold finger 40 described in Figs. Do.

또한 슬롯홈(50)에는 삽입홈(30)과 동일한 암골드핑거부가 형성되어 있게 된다. 따라서 슬롯홈(50)의 암골드핑거부와 슬롯(13)에 형성되는 핑거부(51)가 정합되게 된다. In addition, the slot groove 50 is formed with the same female gold finger portion as the insertion groove (30). Therefore, the female gold fingers of the slot groove 50 and the finger portion 51 formed in the slot 13 is matched.

이상 첨부도면을 참조하여 본 발명의 바람직한 실시예를 사용하여 상세히 설명하였으나, 본 발명의 범위는 특정 실시예에 한정되는 것은 아니며, 이 기술분야에서 통상의 지식을 습득한 자라면, 본 발명의 범위에서 벗어나지 않으면서도 많은 수정과 변형이 가능함을 이해하여야 할 것이다. 따라서 본 발명의 보호범위는 첨부된 특허 청구범위에 의하여 해석되는 것이 바람직할 것이다. Although the above has been described in detail with reference to the accompanying drawings, preferred embodiments of the present invention, the scope of the present invention is not limited to the specific embodiments, and those of ordinary skill in the art, the scope of the present invention It should be understood that many modifications and variations are possible without departing from the scope of the invention. Therefore, the protection scope of the present invention will be preferably interpreted by the appended claims.

이상에서 설명한 바와같이 본 발명은 메인PCB에 부품별로 슬롯모듈을 구성함으로써 모델간 변경 및 확장이 가능하게 되는 효과가 있다.As described above, the present invention has an effect of allowing a change and expansion between models by configuring a slot module for each component in the main PCB.

또한 본 발명은 다른 효과로써는 메인PCB에 부품별로 슬롯모듈을 구성함으로써 하드웨어 설계기간을 단축시킬 뿐만 아니라 각 단위부품의 재고관리가 용이해지는 점을 들 수 있다.In addition, the present invention is that by configuring the slot module for each component on the main PCB, not only shorten the hardware design period, but also facilitate inventory management of each unit part.
